Line 1:
'''Majority Approval, Minimum Pairwise Opposition''' or '''MAMPO''' is one method devised by [[Kevin Venzke]] for the purpose of showing that the [[Favorite Betrayal criterion]], the [[Strong Defensive Strategy criterion]], and the [[Strategy-Free criterion]] are mutually compatible.
 
Another method with these properties is [[Majority Defeat Disqualification Approval]].
Line 8:
The ''score'' for candidate ''X'' against candidate ''Y'' is equal to the number of voters ranking ''X'' above ''Y''. The ''max score'' of candidate ''X'' is the largest score of any other candidate against ''X''.
 
If fewer than one candidatenobody is approved by more than half of the voters, then the candidate approved by the most voters is elected.
 
Otherwise, the candidate with the lowest max score, who is approved by more than half of the voters, is elected.
